Had a UK-bought A3 for a week (last week) but had to return it due a malfunction and the back of the case deforming. Probably a dodgy battery that expanded and bulged out the case.

I'm waiting for a replacement A3 but in the meantime, I wanted to get a rough idea of how common this problem is.

So, please can all past and present A3 owners join the thread, perhaps mentioning how bad the 'bulge' was (I'll post a photo of mine later), after how many hours/days/weeks the problem was noticed, which country it was bought in, roughly when, etc.

My A3 hasn't bulged, I've had it for over a month now. Bought it off of e-bay in the US. I'm not 100% sure yet, but I know that LiPo batteries(The batterys in the cowon players) will bulge if you over charge them, or run them to dead. So if I got an A3 the first thing I'd do is run it to dead, then over charge it, so I can see if I got a faulty one right off.
